Propane tanks are made to hold liquid propane in amounts that are usually between 250 and 60,000 gallons. These storage tanks are made of steel. In the U.S., the American Society of Mechanical Engineers certifies that they meet the requirements for safely withstanding the pressures, temperatures, and environmental conditions needed for storing propane.
They are made to be installed horizontally or vertically, but most of them are made to be installed horizontally. Propane tanks are made to be moved empty, and propane bobtail delivery vehicles or propane transports are used to fill them up. A propane tank can be used to store propane as long as the valves and gauges are still working and the tank shell hasn’t been damaged by rust, fire, or physical damage.
The propane industry has high expertise in tanks, how to install them right, and the rules and procedures for fixing tanks and systems they work on. People who don’t have a license are advised not to try to fix or change their tanks, both for safety and to keep them working. Because the policies and safety methods in the propane industry change, only people familiar with the codes and regulations should install and maintain the Gas tanks.
